A Polygen Model for Heterogeneous Database Systems: The Source Tagging Perspective

Summary: Introduces a polygen model for tagging both base and intermediate data sources in heterogeneous/federated databases. Provides data-driven dynamic translation of polygen queries into local queries, enabling provenance-aware integration and supporting reconciliation and conflict handling.
